Calculating Cfu Per Ml

Calculating Cfu Per Ml. Cfu/100 ml = (# of colonies counted ÷ sample volume filtered in ml) x 100 (cfu = colony forming units). The last pfu rely for every plate is n × 10 × d pfu/ml, the place n is the variety of plaques noticed and d is the worth from the dilution.

Then Second Dilution Gives 8 Colonies Then 8*100 = 800.

Cfu per ml is not depend on dilution, think first dilution give 80 colony then 80*10 = 800 cfu/ml. So multiply the total dilution by 1/10 for the amount added to the plate. Cfu measures only viable cells and is represented as cfu = (nc*df)/vc or colony.
